The Growing "Contentful" Gap
Read OriginalThis technical article analyzes a gap in Chrome's performance metrics, where First Contentful Paint (FCP) and Largest Contentful Paint (LCP) define 'contentful' elements differently. It details how LCP now uses a bits-per-pixel (bpp) entropy threshold for images, which FCP ignores, and examines how SVG elements are treated. The piece includes a demo and real-world examples illustrating these discrepancies and their impact on web performance measurement.
